GAS BURNER.

Application filed June 19, ieei.

This invention relates to gas burner. More particularly it comprises agas burner of the type wher in air is mixed with the gas atone end of said burner and the mixture consumed at the other end of said burner, the constructional features of said ap iratus insuringthe proper proportions of air and gas and rate of fiow'to the jet end of said burner and the having characteristics insuring perfect combustion.

The principal object of the present invention to improve the construction of gas burners of the type referredto. Another objcct of the invention is to provide a novel form of jet or nozzle for a burner which will operate in a more efficient man than those heretofore known. A further object of the invention is the provision of means for adjusting such jet to any desired degree of angularity with respect to the gas passageway. Other objects of the invention will appear in the course of the following description. To the accomplishment of the fore going and related ends, said invention, then consists of the means hereinafter fully described and particularly pointed out in the claims. I

The annexed drawing and the following description set forth in detail certain struc ture embodying the invention, such disclosed means constituting however,but one of various structural forms in which the principle of the invention may be used.

in said annexed drawing 2 Fig. 1 is a top plan view of a gas burner embodying the features of the invention Fig. 2 is a central longitudinal sectional view of the structure shown in Fig. 1, with the nozzle portion of the device shown below the plane of the tube section instead of above said section as in Fig. 1; Fig. 8 is a fragmentary plan view showing the connection of the mixing tube with the nozzle section of the burner; Fig. 4 is a fragmentary sectional view show ing the off-set marginal flanges at the meet ing edges of the upper and lower so :tions of the nozzle portion of the burner, said view being taken along the line 4ld shown in Fig. 3, looking in the direction of the arrows; Fig. 5 is an inside plan View of one of the members of the nozzle portion of the burner, showing the construction and spacing of the lugs at the forward edge thereof; Fig. 6 is a front elevation of the forward edge of the nozzle section of the burner with the preferred form of lugs; and Fig. 7 is a View similar to Fig.

Serial No. 3'21,008.

6, showing a somewhat different form of lugs As is clearly shown in the drawing, the gas burner con'iprises a mixing tube 1 and a jet or nozzle section 2. The mixing; tube prefer ably comprises a longitudinal tube having an outwardly flared outer end 3 pre r-ably formed on a 4-inch indius said flared portion merging with the body of the tube at its point of narrowest diameter. From said point the tube increases in diameter at the rate of one degree per unit of length and ter minutes in. a substantially horizontal aperture equal to the maximum width of said tube. Said aperture is surrounded by a projecting flange "I on the inner edge of the tube providing I an annular shoulder outwardly thereof. The base of the nozzle portion of the burner is provided with an aperture. of a size equal to that in the tube, about which a shoulder 6 and flange 7, complementary to those of thetube are formed. Said shoulders and flanges are adapted to in'tereng;age and the apertures in the tube section and nozzle section of the burner are thus kept in register through all angular adjustments of the nozzle section. in standard installations the burner section is placed above the tube section as is shown in Fig. 1. The two parts are held in assembled relation by means of a bolt 11 passing centrally through. the rcgistering apertures of the two sections and through bolt holes 12, 13. formed in the upper plate of the burner section and in the base of the tube section, respectively. The tube section may be somewhat thiclrenciil at the point where the bolt penetrates the same an d is provided with a flattened base 14;, against which the adjusting nut bears. The nozzle section of the burner preferably is formed of a pair of plates of segmental outline, the lowermost plate 15 having a hollowed central. portion of increasing depth toward its point of attachment to the tube, and the upper plate 16 being; of substzuitially flat sluipc. The forward edge of each of said plates is pro vided with a series of marginal lungs or PM?- jections 17. These lugs preferably have substantially flat exterior faces 18 confer-minp; however, to the slight curvature of the outer edge of the nozzle section and rounded inner faces 19, as is shown more particularly in Fig. 5 of the drawing.

The lugs are each formed with an enlargement 21 stepped or offset from the main body portion on the inner side thereof. In addition to being rounded the inner faces of the l; is

jet or lugs are slightly inclined or beveled so as to provide end faces of reduced area. In the form of lug 22, shown in Fig. 7, each lug is solid, or undivided, but in the preferred form of construction shown in Fig. 5 and Fig. 6 each lug is notched or is formed of two complementary halves 23, 24, which are placed together so as to have a combined exterior outline similar to that of the solid lug shown in Fig. 7 Thus space is provided centrally of each lug radial to the arc-shaped outer edge of the nozzle member. i i hen the p .ates are engaged with each other their meeting edges are sealed about the sides and back with any suitable solder or cement, and at their forward edges the oppositely positioned projecting elements provide a passageway for the gases of combustion. The side edges 20 are preferably flanged.

In addition to the method of securing the marginal edges of the two sections of the nozzle portion of the device together, it has been found desirable to place at an approximately central position a securing bolt 31 through apertures 3L, 33, formed through said plates, strengthening ribs 34: and bosses 35 also being provided adjacent said apertures.

lhe hollowed portion of the nozzle, as stated, preferably becomes slightly less in height and greater in width. in direction from the point of pivotal support to the apertured nozzle. The irregular outline of the passageway through which the fuel. gases emerge is of much importance. Said passageway is continuous from end to end across the arc-shaped front edge of the nozzle and presents a sinuous outline, the top and bottom portions of which present an area for the passage of gas, considerably larger than the side portions thereof. This passageway, as viewed from the front of the nozzle, shows a series of steps and inclined side faces and the ends of each of the projecting lugs are blunt straight edges parallel to the bases thereof.

At the rearward end of the gas mixture tube a crosssupport 4-1 is provided, said support preferably having a central enlarge ment 42 of cylindrical shape to receive the gas supply nozzle. A. set-screw 4L3 engaged within said cylindrical enlargement provides a means of clamping said gas supply nozzle in adjusted position.

Other modes of applying the principle of my invention may be employed instead of the one explained, change bein made as regards the structure herein disclosed, provided the means stated by any of the following claims or the e uivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. A burner for gas stoves, comprising a. gas mixing section, an elongated nozzle section having peripheral orifices at its forward end, said mixing section being provided with ahorizontally positioned aperture and said nozzle section being provided at its rearward end adjacent its under side with a similar aperture, circular bearing surfaces adjacent said apertui sfor adapting the parts to have movement relative to each other to provide flame positioning adjustment, a bolt positioned centrally of said apertures and bearing the outer face of said mixing and nozzle sections for securing the san'ie against movement, and a series of spaced lug. at the forward end of said nozzle section producing a continuous passageway for the fuel gases.

2. A burner for gas stoves, comprising a gas mixin section, an elongated nozzle section having peripheral orifices at its forward end, said mixing section being provided with a horizontally positioned aperture and said nozzle section being provided at its rearward end adjacent its under side with a similar aperture, circular bearing surfaces adjacent said apertures for adapting the parts to have movement relative to each other, a bolt posi tioned centrally of said apertures and bearing against the outer face of said mixing and nozzle sections for securing the same against movement, and a series of spaced lugs formed on the upper and lower portions of the nozzle section of the burner and spaced to form a sinuous passageway for the gases passing through said burner.

3. A burner for gas stoves, comprising a gas mixing section, an elongated nozzle section having peripheral orifices at its forward end, said mixing section being provided with a horizontally positioned aperture and said nozzle section being provided at its rearward end adjacent its under side with a similar aperture, circular bearing surfaces adjacent said apertures for adapting the parts to have movement relative to each other, a bolt positioned centrally of said apertures and hearing against the outer face of said mixing and nozzle sections for securing the same against movement, and a series of lugs having inclined sides and off-set sections intermediately thereof formed on the upper and lower portions of the nozzle section of the burner and spaced to form a sinuous passageway throughout its length for the gases passing through said burner.
